the phase diagram it currently reads “Bi3Te7 (Te)”. The correct label is “Bi7Te3 (Bi)” as shown in the corrected Figure 1.

Figure 1. (a) Bi2Te3 is evaporated in the center of the furnace and decomposes before reaching the substrate placed downstream at its cold end. (b) Simplified Bi−Te phase diagram.1 The growth temperature is marked by a red bar. The inset shows difusion of atoms and molecules (red spheres) toward TiO2 nanoparticles. (c) These clusters incorporate TiO2 catalyst particles (brighter circular areas), as can be seen in the STEM image. Their composition is Bi2Te (darker region), surrounded by an outer Te shell (brighter region). The composition is given in atomic-%, as measured by EDX. (d) Freestanding belts (SEM micrograph) grown from a flat base (dark). The belts are transparent so that underlying plates (indicated by white outlines) are visible. (e) Image of the base of a belt showing several particles at its root (inset) which potentially act as an initial nucleation center. The belt has been rotated manually by 180° about its long axis (white arrow). © XXXX American Chemical Society
